mm-multinbr button or FAC. After the new party begins alerting, the
controller may hit CONFERENCE to add the party to the existing
conference on hold.
Coverage. Multimedia calls to a Basic mode complex are subject to the same
coverage criteria as voice calls and follow the coverage path administered for the
voice station of the Basic multimedia mode complex.
If a plain voice station or a Basic mode complex is the covering party, the
answering voice station will receive audio only. If all voice stations in the
coverage path have the station form Early Answer field set to n and the originator
of the multimedia call was not a local Enhanced mode complex, the answering
station will hear hourglass tone.
If an Enhanced mode complex is the covering party, the answering voice station
will receive voice and video. If all voice stations in the coverage path have the
station form Early Answer field set to n and the originator of the multimedia call
was not a local Enhanced mode complex, the answering station will hear
hourglass tone.
Coverage: Multimedia calls and off-net call coverage. If the principal station’s
coverage path include a remote coverage point, the multimedia call will cover
off-switch as voice only. If the call is unanswered off-switch and proceeds to the
next coverage point on-switch, the multimedia nature of the call is preserved.
Coverage: Multimedia calls and coverage to voice mail. Voice mail systems
such as AUDIX are typically the last point in a coverage path and are usually
implemented as a hunt group. In order to guarantee that the originator of an H.320
multimedia call hears the voice mail greeting, the hunt group that defines the list
of voice mail ports should have the Early Answer field on the hunt group set to y.
This field will have no effect on voice calls to the voice mail system.
Call Detail Recording. Each channel of a 2-channel call generates a separate
CDR record.
Data Collaboration
Once you have established a multi-point video conference, multi-point T.120 data
collaboration may be enabled for that call. This will allow all video parties on the
current conference to collaborate.
T.120 Data conferencing is made possible through the Expansion Services
Module (ESM) which is an adjunct to the DEFINITY ECS. Up to six parties may
participate in a single data conference, and up to 24 parties may use ESM facilities
for data collaboration at any given time.
